Answer:
Step-by-step explanation:
120=x²×h=x×xh
xh=120/x
surface area A(x)=2x²+4x×h=2x²+4xh=2x²+4×120/x=2x²+480/x
Answer:
y = 250
Step 1:
To solve, we plug in 50x for y.

Then, we subtract the 10x from the right side. Our goal is to get the x by itself first.

Then, we divide both sides by 40, since we have to get the x by itself.

x = 5
Step 2:
Now that we found x, we plug in 5 to the original equation and solve from there.

y = 250
The values of the number is 43
x+21=64
subtract 21 on each side
x = 43
Answer:
Bro this is hard answer is 0.17 or 2/12
